We're dividing 643606 by 10 
Our goal is to divide 643606 by 10.

On to step 1:
6 divided by 10 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 10

Step 2:
When dividing 64 by 10, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 60 from 64 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 10

On to step 3:
10 can be fit into 43 4 times, resulting in a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtracting 40 from 43 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 10

On to step 4:
When dividing 36 by 10, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 643.0
The remainder is 6 after subtracting 30 from 36.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 10

Step 5:
60 divided by 10 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6436.0
The remainder is 0 after subtracting 60 from 60.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 10

Moving on to step 6:
10 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 64360.0
Subtracting 0 from 6 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
The number 10 fits into 60 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 64360.6
Deduct 60 from 60 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 64360.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 64360.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 64360.6, with a leftover of 0.0.
